Accueil » Areas of expertise » Drinking water, sanitation and waste management

Because of the fundamental role that they play in the urban fabric, drinking water, sanitation and waste management services are central to local development policies. They are necessary to improve living conditions for populations, and their extension brings up the stakes of territorial performance and social equity.

Despite the capital investments in drinking water, sanitation and waste management services, the results are still unsatisfactory in light of the goal of ensuring universal access to services. Public policy prescriptions have followed each other without providing any definitive solution to the issues of service financing and governance. Many challenges remain to be overcome to attain universal access to sanitation, waste management and drinking water services. The declarations at the Sixth World Water Forum in Marseille in 2012 are not enough; more financing and more inclusive sectoral policies are needed.
For 30 years, GRET has helped improve drinking water and sanitation access conditions. Its action is guided by an ultimate goal: guarantee everyone fair, sustainable access to quality services. Based on innovation efforts, GRET’s projects comply with the requirements of being suited to the local context. Its methods combine strengthening actors in the fulfillment of their missions (contracting authority, management, service regulation), organizing multi-actor models of governance at various scales, and elaborating technical, financial and organizational solutions that build on local dynamics.
